When I try to debug I get an error

Configuration

Cache 2016.2 running on fully patched minimal CentOS 7 install. No Firewall.

Atelier running on Centos 7 Desktop. No Firewall.

I was able to build and compile classes from Atelier.

When I try to run a routine or some class code from Atelier I get an error.  It tells me to look at the Network Activities view.

When I do that I see the following:

I'm wondering If I have something not set up correctly.
